    Abstract: The present invention provides an improved amorphization/templated recrystallization (ATR) method for fabricating low-defect-density hybrid orientation substrates. ATR methods for hybrid orientation substrate fabrication generally start with a Si layer having a first orientation bonded to a second Si layer or substrate having a second orientation. Selected regions of the first Si layer are amorphized and then recrystallized into the orientation of the second Si layer by using the second Si layer as a template. In particular, this invention provides a melt-recrystallization ATR method, for use alone or in combination with non-melt-recrystallization ATR methods, in which selected Si regions bounded by dielectric-filled trenches are induced to undergo an orientation change by the steps of preamorphization, laser-induced melting, and corner-defect-free templated recrystallization from the melt.

    Abstract: The present invention provides an improved amorphization/ templated recrystallization (ATR) method for fabricating low-defect-density hybrid orientation substrates. ATR methods for hybrid orientation substrate fabrication generally start with a Si layer having a first orientation bonded to a second Si layer or substrate having a second orientation. Selected regions of the first Si layer are amorphized and then recrystallized into the orientation of the second Si layer by using the second Si layer as a template. The process flow of the present invention solves two major difficulties not disclosed by prior art ATR methods: the creation of "corner defects" at the edges of amorphized Si regions bounded by trenches, and undesired orientation changes during a high temperature post-recrystallization defect-removal annealing of non-ATR'd regions not bounded by trenches. In particular, this invention provides a process flow comprisng the steps of (i) amorphization and low-temperature recrystallization performed in substrate regions free of trenches; (ii) formation of trench isolation regions that subsume the defective regions at the edge of the ATR'd regions, and (iii) a high-temperature defect-removal anneal performed with the trench isolation regions in place.

    Abstract translation: 本发明提供了用于制造低缺陷密度混合取向基底的改进的非晶化/模板重结晶(ATR)方法。 用于混合取向衬底制造的ATR方法通常从具有第一取向键合到具有第二取向的第二Si层或衬底的Si层开始。 第一Si层的选定区域是非晶化的,然后通过使用第二Si层作为模板,再结晶成第二Si层的取向。 本发明的工艺流程解决了现有技术ATR方法未公开的两个主要困难:在由沟槽限定的非晶化Si区域的边缘处产生“角部缺陷”,以及在高温后再结晶缺陷 - 不由沟槽限定的非ATR区域的去除退火。 特别地,本发明提供一种工艺流程,包括以下步骤:(i)在没有沟槽的衬底区域中进行的非晶化和低温重结晶; (ii)形成沟槽隔离区域,其包围在ATR'd区域的边缘处的缺陷区域,以及(iii)在沟槽隔离区域中进行的高温缺陷去除退火。

    Abstract: The present invention provides a semiconductor material that has enhanced electron and hole mobilities that comprises a Si-containing layer having a crystal orientation and a biaxial compressive strain. The term “biaxial compressive stress” is used herein to describe the net stress caused by longitudinal compressive stress and lateral stress that is induced upon the Si-containing layer during the manufacturing of the semiconductor material. Other aspect of the present invention relates to a method of forming the semiconductor material of the present invention. The method of the present invention includes the steps of providing a silicon-containing layer; and creating a biaxial strain in the silicon-containing layer.

    Abstract: Strukturen zum Abschirmen elektromagnetischer Störungen und Verfahren zum Abschirmen eines Objekts vor elektromagnetischer Strahlung bei Frequenzen, die höher als ein Megahertz sind, beinhalten im Allgemeinen das Bereitstellen hoch dotierter dünner Lagen aus Graphen um das abzuschirmende Objekt herum. Die hoch dotierten dünnen Lagen aus Graphen können eine Dotierstoffkonzentration, die höher als > 1e1013 cm–2 ist, die dahingehend wirksam ist, dass die elektromagnetische Strahlung reflektiert wird, oder eine Dotierstoffkonzentration von 1e1013 cm–2 > n > 0 cm–2 aufweisen, die dahingehend wirksam ist, dass die elektromagnetische Strahlung absorbiert wird.
